Description

  The present invention relates to a video apparatus that receives video via broadcast or a network, and more particularly to a search method for searching using broadcast programs and video data based on keywords.

  In digital broadcasting such as terrestrial digital broadcasting, program schedule information such as program names and program contents for a certain period after the present is distributed. The user can search for a program to be viewed from the program guide information, and can make a viewing reservation or a recording reservation. In recent years, video apparatuses have a function of streaming viewing and downloading viewing of video data via a network. These devices have a function of acquiring information about titles and contents attached to the video data. The user can search for video data to view from this accompanying information.

  The user must search for a desired program from the program guide information and the accompanying information of the video data. Therefore, recent video apparatuses have a search function for searching for a desired program from the program guide information and the accompanying information of the video data.

  In Patent Document 1, a search condition pattern used in a search process for searching for a program to be viewed or reserved for recording is stored for each program genre in advance, and when searching for a program related to the program currently being viewed. A receiving apparatus is disclosed that can identify a genre of a viewing program and display a search condition pattern corresponding to the identified genre as a search method item in a menu. With this configuration, it is possible to smoothly search for programs related to the program that the user is viewing.

  However, a conventional receiving apparatus must determine a search condition corresponding to a genre in advance. In addition, when searching for a program not related to the program being viewed, it is necessary to change the genre. Also, there may be a case where there is no appropriate search condition for the program that the user wants to watch.

  Therefore, although it is easier to find a desired program when actually searching with a free keyword, it is not always possible to find a desired program with a single search, and a search with various keywords is attempted until a desired program is found. Often trial and error.

  Therefore, the present invention stores the keyword used for the search when the program is actually used, such as watching a program found from the search result or recording a reservation, and presenting it as a keyword candidate at the next search. This is intended to improve the convenience of search.

  In order to achieve the above object, a video apparatus according to the present invention is a video apparatus capable of receiving and playing back a television signal, and an input means for inputting a keyword and a program for extracting program information from the received television signal. Program search for searching for a program related to the keyword by comparing the information extraction means, the program recording means for recording the program, and the program information extracted by the program information extraction means and the keyword input by the input means The program recorded by the program recording means is retrieved from the means, the search keyword storage means for storing the program searched by the program search means, the keyword used in the search, and the keyword recorded by the search keyword recording means And a keyword extracting means for extracting a keyword.

  According to the above configuration, it is possible to provide a video apparatus capable of extracting and presenting a keyword that has a high possibility of searching for a program desired by a user from keywords used for searching in the past.

  The receiving means 101 extracts broadcast data from a radio signal such as broadcast.

  The decoding unit 102 decodes the broadcast data received by the receiving unit 101 into a video signal and an audio signal, and extracts program guide information such as a program name and program content.

  The viewing control unit 103 selects a broadcast instructed to the receiving unit 101 in accordance with an instruction from a user input by an operation unit (not shown), and writes information on the selected program in the memory 105.

  The reservation control unit 104 stores the reservation information and writes the reserved program information in the memory 105 in accordance with an instruction from the user input by an operation unit (not shown).

  The memory 105 stores the keyword used for the search by the keyword search unit 106 and the program information extracted as a result thereof in association with each other, and also extracts the program information written from the viewing control unit 103 and the reservation control unit 104. The program information is stored in the data format shown in FIG.

  The keyword search means 106 extracts a program related to the keyword from the program guide information using the keyword input or selected by the user with the keyword input means 109 and stores it in the memory 105.

  The keyword extraction unit 107 extracts keywords to be used as candidates for the next search from the information stored in the memory 105.

  The content search control unit 108 presents the keyword extracted by the keyword extraction unit 107 to the user in accordance with a content search instruction from the user by an operation unit (not shown).

  The keyword input unit 109 transmits the keyword input by the user to the keyword search unit 106. In the present embodiment, the keyword input means 109 is constituted by a remote controller, and by using it, a keyword is input from a menu screen displayed on the video display means 111 described later. However, in the present embodiment, the keyword input unit 109 is configured by a remote controller, but it may be a touch panel screen mounted on the video display unit 111 or a button arranged on the video device 100.

  The display control unit 110 generates a screen for the user to perform a search operation, and displays the screen on the video display unit 111 connected to the video apparatus 100 together with the video signal output from the decoding unit 102.
